Newly discovered mineral petrovite could revolutionize batteries

Russian scientists discover a new mineral in the volcanic area of Kamchatka in the country's far east.The mineral dubbed "petrovite" can be utilized to power sodium-ion batteries.Batteries based on salt would be cheaper to produce than lithium-ion batteries. Researchers from St. Petersburg University in Russia found a beautiful new mineral species called "petrovite," created in the volcanos of the remote region of Kamchatka in the country's far east.The research team that found petrovite was he...

Scientists discover a new mineral

The research team headed by Stanislav Filatov, Professor at the Department of Crystallography at St Petersburg University, has discovered a new mineral species in Kamchatka - petrovite. The scientists named the find in honour of Tomas Petrov, an outstanding crystallographer and Professor at St Petersburg University. He together with his students Arkady Glikin and Sergei Moshkin, was the first in the world to create a technology for growing jewellery malachite.

A putative mechanism that switches brain pathology from anxiety to depression discovered

In experiments on mice, putative mechanisms for switching brain pathology from a state of experimental anxiety to depression have been discovered by the international team of researchers led by scientists from St Petersburg University (Russia). In the long term, this discovery could make it possible to create new, more effective drugs for mental disorders in humans.

To think like a dinosaur

Palaeontologists from St Petersburg University have been the first to study in detail the structure of the brain and blood vessels in the skull of the ankylosaur Bissektipelta archibaldi. It was a herbivorous dinosaur somewhat similar in appearance to a modern armadillo.

Scientists find out which of the metazoans has the smallest known genome

Researchers at St Petersburg University have deciphered the Intoshia variabili gene, the smallest representative of the parasite from the Orthonectida group. At present, its genome is proved to be smallest among all metazoans and includes only 5,120 genes. Phylogenetic relationships of Orthonectida have remained controversial for a long time. According to recent data from St Petersburg University scientists, these parasites are close to Annelida.

High ferritin levels may indicate severe COVID-19

Professor Yehuda Shoenfeld is Head of the Laboratory of the Mosaic of Autoimmunity at St Petersburg University and founder and Head of the Zabludowicz Center for Autoimmune Diseases (Israel). During the Cradle of Virology online conference, he spoke about the correlation between the severity of COVID-19 symptoms and high levels of ferritin. It turns out that elevated ferritin concentrations are associated with an increased production of special signalling molecules, which can lead to complicatio...

A rare snail living on wood is discovered in the Arctic ocean

Postgraduate student Ekaterina Krol and Senior Research Associate at the Department of Applied Ecology of St Petersburg University Ivan Nekhaev have found a marine snail from the subclass Neomphaliones in a collection from the Soviet Arctic expeditions of the 1930s. For over 70 years, it has been mistakenly placed in another family of marine molluscs. It is noteworthy that representatives of the subclass Neomphaliones have been found in such specific habitats as sunken wood and hydrothermal vent...

Dralyuk’s 1917.

It’s high time I spread the word about Boris Dralyuk’s brilliant compilation 1917: Stories and Poems from the Russian Revolution. Fortunately, I don’t have to expend a lot of effort explaining to you how brilliant it is, because Caryl Emerson has done it for me in this TLS review (happily available even to nonsubscribers). I’ll just quote a few paragraphs to whet your appetite and send you to the TLS link for the rest (and to Wuthering Expectations for another rave): Dralyuk must put these lyr...
